Boston solar is different from suburban solar. We have the specialized experience to handle every challenge the city presents.
Flat roof ballasted systems designed for multi-unit ownership. We handle virtual net metering, shared metering allocation, and credit splits across all three units. Our structural engineers assess every triple-decker roof before installation.
Beacon Hill, Back Bay, South End — we navigate Boston Landmarks Commission reviews, architectural requirements, and all-black panel specifications. We present to historic commissions and handle the entire approval process.
Shared roof agreements, condo board presentations, unit-owner vote coordination, and virtual net metering allocation. We guide condo associations from initial proposal through installation and interconnection.
Deep experience with Boston ISD building and electrical permits, fire department sign-off, and Eversource interconnection. We submit permits electronically and follow up actively to minimize delays.
We install solar across every Boston neighborhood — from Beacon Hill brownstones to Dorchester triple-deckers.
Plus adjacent communities: Cambridge, Somerville, Brookline, Quincy, Newton, Watertown, Medford, Malden

Not every solar installer can handle Boston. Here is why urban experience matters.
| Factor | Boston | Suburbs |
|---|---|---|
| Roof Type | Mostly flat roofs — ballasted racking, structural assessment required | Mostly pitched roofs — standard rail-mount penetrating racking |
| Permitting | Boston ISD + fire dept sign-off. Historic district review in 9+ neighborhoods | Standard municipal building permit, typically 1-2 weeks |
| Shading | Building-to-building shading common. Narrow lots, adjacent rooflines | Tree shading is primary concern. Generally wider lot spacing |
| Access | Narrow streets, no parking, boom truck coordination, street permits | Driveway access, easy truck staging, no street permits |
| Building Type | Triple-deckers, condos, brownstones — multi-owner coordination | Single-family homes — one owner decision |
| Utility | Eversource only — $0.28/kWh, specific interconnection process | Mix of Eversource, National Grid, or MLPs — rates and rules vary |
“NuWatt handled our triple-decker solar install from start to finish. They figured out the VNM credit allocation between units, got our permits through Boston ISD in under 3 weeks, and enrolled us in SMART before the cap. All three families are saving money now.”

“Living in a historic district, I was told by two other companies that solar was impossible. NuWatt got us approved by the Landmarks Commission with all-black panels. The system has been running for 8 months and our Eversource bill went from $280/month to under $40.”
David K.
South End, Boston
“We added solar and a battery through NuWatt. They handled the ConnectedSolutions enrollment and we are earning $275/kW from Eversource demand response on top of our net metering credits. Payback is tracking to under 7 years. No federal tax credit needed.”
